I also Have datum points, and because I almost always use the same set up,
my balance points rarely change, and I would also be physically set up in
10 minutes or so, but I did include the star alignments in my estimate.
How long this part of the routine takes will obviously depend on the accuracy
that is desired. Then finally the PA has to be checked, and adjusted if necessary.[The last part only if doing imaging].
